Study Notes
Drug Classification
- Drugs can be classified by various factors:
- Therapeutic use (e.g., antimicrobial, antidiabetic, analgesic)
- Mode of action (e.g., receptor blocker, enzyme inhibitor)
- Site of action (e.g., loop diuretic, cell wall inhibitor)
- Molecular structure (e.g., glycoside, alkaloid, steroid)
Non-Proprietary Names (Generic Names)
- Benefits of using generic names:
-
Clarity: Generic names reveal the drug class. Examples:
- Names ending in "-azepam" (e.g., diazepam, nitrazepam) are benzodiazepines.
- Names ending in "-olol" (e.g., atenolol, metoprolol, bisoprolol) are beta-adrenoceptor blockers.
- Names ending in "-pril" (e.g., lisinopril, enalapril) are ACE inhibitors.
- Names ending in "-floxacin" (e.g., ciprofloxacin, levofloxacin) are quinolone antibacterial agents.
- Economy: Often cheaper than proprietary (brand-name) drugs.
- Convenience: Pharmacists can supply any available version of the generic drug.
-
Clarity: Generic names reveal the drug class. Examples:
Proprietary Names (Brand Names)
- Reasons to use brand names:
- Consistency: Maintains consistent product quality and bioavailability.
- Critical for Low Therapeutic Index Drugs: Essential for drugs like digoxin and warfarin, where dosage variations heavily impact patients.
- Complex Formulations: Necessary for specialized drugs (e.g., sustained-release formulations).
- Mixture of Drugs: Used for combinations of drugs that cannot easily be written out as ingredient lists.
- International Use: Helpful for international travelers with chronic illnesses, as brand names vary between countries.
- International Non-Proprietary Name (INN): Beneficial for international travelers.
